What’s the default size of the bufferedwriter class?
Here, the internal buffer of the BufferedWriter has the default size of 8192 characters. However, we can specify the size of the internal buffer as well.

Can a bufferedwriter write a substring as an int?
Substrings, chars, ints. BufferedWriter handles more than strings. It can write just a part of a string—a substring (specified with a start index and length). Char: To write a char, we must use the append method. The write method will not work—it treats chars as integers.
